Autostart animated slide show

I am trying incorporate an animated slide show built in Powerpoint that also has audio.

  1. I’ve exporting each slide as video - good, but won’t auto play
  2. Made a gif of each slide - great (autoplays) but no audio
  3. Made a gif and added the split off audio as an audio file - no good - audio doesn’t auto play

Is there something I haven’t thought of?
Thanks!
